Have You Taken the Gold-Medal Challenge Yet? Today, Work Your Bod Like a Speed Skater

If you guys haven't tried our gold-medal challenge, you need to: we've got each Olympic day pegged to a specific sport you'll be watching -- and got some moves from Nike Master Trainer Holly Rilinger if you wanna work it like an Olympic pro. Come back each day and unlock a new workout to challenge yourself!

Today, women competed in the 500 m short track sprint — that’s speed skating, folks — which is basically a roller derby on ice. Rillinger suggests trying squat jumps (pictured), since these athletes need quick reaction skills and well as a solid balance of power, balance and finesse.
